As suggested from Komori-kun, I measured the TF from PRCL displacement to DARM displacement to evaluate the noise coupling from PRCL displacement to DARM displacement (fig1).
Unforetunately, IFO was down during the measurement but TF from 20Hz to 300Hz was measured.
But we need some more investigation for the noise projection
As pointed out by Komori-san, we need tto multiply the effect of the OLG 1/(1+G) to the projection of PRCL, so I performed it.
